With the increasing demand for high-frequency and high-speed transmission, PEI (Polyetherimide) materials have achieved a dielectric constant below 3.0 (at 1 GHz) through molecular structure optimization (such as the introduction of fluorinated groups), making it a key material solution for 5G millimeter-wave connectors.
Compared to traditional materials like PBT/PPS, PEI can extend the lifecycle of connectors by 3-5 times and reduce the failure rate by 82% under extreme conditions (verified by ASTM data). This combination of reliability and cost-effectiveness is driving its penetration rate in the high-end electronic components sector to over 47% (2023 market research data). As electronic devices move toward nanoscale precision and terahertz transmission, PEI continues to empower connector technology innovation through breakthroughs in material science. This is not just an evolution of engineering plastics but also a genetic upgrade in the reliability of smart hardware.
In the field of precision electronics, PEI (Polyetherimide) is reshaping connector standards as a revolutionary material. This high-performance engineering plastic is replacing traditional materials and becoming the new industry benchmark, thanks to its six core advantages:
1. **Inherently flame-retardant V0@1.5MM and above**
2. **High-temperature resistance**, capable of long-term use at 160-180°C
3. **Excellent mechanical properties**, including high strength, high rigidity, and superior wear resistance
4. **Outstanding electrical insulation performance**
5. **Chemical resistance**
